HAY-PRESS.

Specification of Letters Patent.

Patented Feb. 20, 1906.

Application filed December 14, 1904. Serial No. 236,881.

To all whom, it may concern:

Be it known that I, ALEXANDER LORENZ, a

. citizen of the United States of America, and

a resident of San Antonio, in the county of BeXar and State of Texas,have invented certain new and useful Improvements in I-Iay- Presses, ofwhich the following is a specificatlon.

, This invention relates to baling-presses, and particularly to thatform of balingpresses operating on a horizontal plane and wherein aplunger is continuously reciprocated while the material to be pressed isbeing fed into the press-chamber.

The object of the invention is the construc tion of a press of thisclass in a manner such that the continuous operation of thereciprocating plunger may be insured and greater efliciency for thepress effected.

To this end the invention consists in the construction and combinationof parts hereinafter described and claimed.

In the accompanying drawings, which form a part of this specification,Figure 1 is a top view of the entire hay-press. Fig. 2 is a side viewthereof, and Fig. 3 a front view, while Fig. 4 is a top view, on anenlarged scale, of the ratchet-wheel and looped pawl, showing thecooperation thereof; and Fig. 5 is a side view of the parts seen in Fig.4.

The case of the baling-press is indicated by A,the press-head, or thehead of the plunger, is indicated by B, and the pole thereof by O.

D represents the pitman, and F the crank, of the vertical crank-shaft,to which the pitman is journaled, said pitman being pivoted to the poleby means of the bolt E. The crank-shaft is ournaled at its upper ends inthe powerframe, which, as shown, is sup ported upon a pair of wheels inthe wellknown manner. Upon the crankshaft above the power-frame is idlymounted the socket G of the power pole or sweep, and above this socket,or in reality in a recess there in, is located the ratchet-wheel K,which is firmly fixed to the upper end of the crank shaft. For engagingthe sweep with the crank-shaft to rotate it a looped pawl J is provided,which is pivoted, as at H, to the sweep-socket Or. To hold this pawl inengagement with the ratchet-wheel, a suitable spring, as L, is provided.The initial position of the plunger is that shown in Figs. 1 and 2,wherein it is represented as ready to begin a compressing stroke. Toreturn the plunger tothis initial position instantaneously andautomatically after each stroke of compression, a spring, as M, isconnected to the power-frame and to the pole O of the plunger.

In the operation of the parts described the sweep is movedcounter-clockwise, the pawl J being held in engagement with one of theteeth of the ratchet-wheel K and until the crank passes dead-center inthe stroke of compression-*that' is, until the plunger has reached itslimit in the act of compressing the material in the baling-case. Then assoon as dead-center is passed the spring M acts to return the plunger toits initial position, thereby swinging the crank about through onehundred and eighty degrees, which movement the pawl J permits by slidingover the teeth of the ratchet-wheel K. In this return movement of theplunger the progression of the sweep is not interfered with, andimmediately upon the completion of said return movement the pawl J againengages a tooth of the ratchet-wheel and the plunger begins anotherstroke of compression.

Changes in the formation and association of the parts described maybemade without departing from the invention.

I claim- I In a horizontal baling-press, the combination, with the caseand base-piece extending forwardly therefrom, of the power-frame mountedon the forward end of the base piece, a crank-shaft journaled at itslower end in the base-piece and'at its upper end in the power-frame andprojecting above it, the plunger-pole mounted in guides on the basepiece, a retractile spring connected thereto and to the power-frame, apitman pivoted to the upper side of the said pole and to the crank ofthe crank-shaft, a collar on the crank-shaft above the crank, a stayconnected to said collar and to the press-case, a sweep-socket mountedidly on the upper end of the crank-shaft and having an arm extendingtherefrom for the attachment of a stay Signed at San Antonio, Texas,this 30th leading to the end of the sweep, a ratchet 10- day ofNovember, 1904. cated in a recess of the sweep-socket and fixed to thecrank-shaft, a looped pawl ALEXANDER NZ 5 hinged to the sweep-socket,and a spring for Witnesses:

holding the pawl in engagement With the EMIL PHILLIPPE,

ratchet, for the purpose set forth. 1 JOHN W. ILLG.
